Table 20: Gold Whistle Communication Options
For ease of setup and diagnostics of CAN communication, RS-232 and CAN can be used
simultaneously.
When the EtherCAT is connected, and FoE in operation, the USB cable connection
must be disconnected.
4.11.1. RS-232 Communication (J2)
The Gold Whistle provides RS-232 with TTL voltage level (Refer to the voltage level in the
technical specification in Section 5.7: Communications). Therefore, to implement standard RS-
232, you must add a RS-232 Line Driver/Receiver on the integration board in order to translate
the TTL logic level to the standard RS-232 voltage level.
The following table describes the Gold Whistle RS-232 pinout:
